Description :
    预置条件：
        1.创建事件触发器：
        CREATE OR REPLACE FUNCTION f_eventtrigger_0009;6()
        RETURNS event_trigger
        LANGUAGE plpgsql
        AS $$ BEGIN
        RAISE NOTICE 'test_event_trigger: % %', tg_event, tg_tag;
        END;
        $$;
        CREATE EVENT TRIGGER start_eventtri ON ddl_command_start EXECUTE PROCEDURE f_eventtrigger_0009();
        CREATE EVENT TRIGGER end_eventtri ON ddl_command_end EXECUTE PROCEDURE f_eventtrigger_0009();
        CREATE EVENT TRIGGER drop_eventtri ON sql_drop EXECUTE PROCEDURE f_eventtrigger_0009();
        2.创建表
        CREATE TABLE t_eventtrigger_0009(id int, col int);
    测试步骤：
        1、COMMENT ON COLUMN t_eventtrigger_0009.id IS 'testid';
Expect      : 
    1、触发执行函数f_eventtrigger_0009;()
